I recently purchased a laptop which has the 2nd generation core i7 2720Q processor (Sandybridge), and according to the specification from Intel, it supports OGL 3.0. DoctorGL and GLView both confirm that the machine has OGL 3.0 support along with GLU 1.2.2.0 from MS, but I'm seeing a dialog box that says, "Missing render-texture extension!" and "No pixel format available!" any time I attempt to use the plugin.

It would seem that this is a potential issue with the GPU plugin, and although I'm able to use the older OGL 1.77 just fine, I wanted to make someone aware just in case.

As you said, the extension may not be supported regardless. Here is a Doctor GL dump; which should I look for? The dialog mentions 'render-texture' but this doesn't follow the extension naming convention and potentially just a generic message...?

Also, it claims no pixel format is found, but Doctor GL shows a multitude available...

Well, either Intel is very lazy on exposing the API in their drivers or the GMA HD on a 2nd gen core i7 processor isn't capable of handling that extension which would make exposing it a waste of time.

The good news is that both the old OGL & D3D plugins work great, and even the new OGL will work decently with some customization; however, if I want to run the new OGL optimally, I'll just resort to the Geforce 555T.
